AMAZING!!!! AMAZING!!!!! AMAZING!!! (Tips included) Guys dont give a second thought, just go for it! I had purchased a useless Bergner knife set Bergner Knife Set, 8-Pieces which came with very blunt knives. So I had to but another Rena Germany Chef's knife Rena Germany - Knife - Chef'S Knives - Black Color - Stainless Steel - 210 Mm from amazon to go about my work. This knife was sharp as hell. Now my stone arrived yesterday and I honed my Bergner knives with it and trust me, they are as sharp as the Rena Germany knife, actually even sharper. It's a must have for your kitchen. It's surprising how low priced it is. Before using this stone, I suggest you watch some videos on Youtube about using combination stones. Tips 1. before sharpening immerse the stone in water and keep it that way until the bubbles stop coming out of stone 2. If you choose to use oil once,(for lubricating) always use oil and same with water. DO NOT SWITCH between oil and water. 3. This stone comes with a double grit. For coarse honing (if your knife is too blunt), use the dark green surface. For getting the fine edge use the lighter green surface where the logo is printed. 4.The packet recommends you to keep a 30° angle, but i personally prefer keeping a 20° to 25° angle for European style knives. Feel free to ask me about anything related to using this amazing stone.
